Title: Method of fabricating foam-filled tires
IPC: B29D30/04
Filed: 1969-04-01
Abstract: 1,216,049. Moulding tyres. DOW CORNING CORP. 1 April, 1969 [2 Aug., 1968], No. 16906/69. Heading B5A. In a method of moulding a tyre containing a foamed material which may completely fill it or leave space for an air cushion with or without an inner tube, a quantity of heat curable tread rubber stock is fed to an annular mould to fill it, a central part of the mould is removed and a band of heat curable foam filler stock containing a heat activatable blowing agent is placed adjacent the inner periphery of the tread stock, the mould is then closed to provide a shaping surface corresponding to that of the desired tyre, and the mould is heated to effect blowing of the agent to create a foamed uncured filler material which is then cured together with all the heat curable stock 5. In the assembly line arrangement of Fig. 2, the tread rubber is first moulded between a mould body 23 and a member 26 from which rubber stock is forced by a piston 29 through ports 28. The stock is partially cured to be self-supporting. The parts 26, 29 are removed and a reinforcement member 12, or a flat belt, placed adjacent the tread, and a member 33 lowered into the mould. Heat curable foam filler is forced from the member 33 by a piston into the member 12, or on to the belt. Alternatively a reinforcement member is not used and the foam filler is applied directly to the inner surface of the tread. The member 33 is now withdrawn and, as shown, a rim 16, 17 is placed within the mould and engages the inner periphery of the member 12, and the tyre beads, if any, are held by the rim; the mould is completely closed by a cover 38 and rotated about its axis to distribute the filler material. The mould is then heated and the filler material expanded to fill the tyre interior; final curing may be effected within the mould or a partial curing within the mould may be followed by removal of the tyre and a final curing outside the mould.

Title: Sheet metal forming by use of detonation waves
Inventor: POORMAN RICHARD MARION
IPC: B21D26/08
Filed: 1952-06-11
Abstract: 742,460. Stamping. UNION CARBIDE & CARBON CORPORATION. June 11, 1952, No. 17036/54. Divided out of 742,387, [Group II]. Class 83 (4). A method of forming sheet metal is characterized by superimposing the sheet metal over a die and directing against the exposed surface of the sheet metal detonation waves produced by igniting a detonatable mixture of a fluid fuel and an oxidizing gas within an elongated container having an open end. A combustible gas, e.g. acetylene, hydrogen, propane, butane, pentane or ethylene is supplied through a pipe 10 and an oxidizing gas, e.g. air is supplied through a pipe 11 to a mixing chamber 12 from where the gaseous charge passes into an ignition chamber 14 provided with a spark plug 15 which is fired by a coil 17, a battery 18 and a cam-operated switch 19 regulated by a variable-speed motor 20. Firing of the plug ignites the charge and a detonation wave travels through a water or air cooled barrel 16 and out its open end. A back-fire arrester may be inserted in the fuel supply line. Liquid fuels such as gasoline may be vaporized and used and also solid fuels such as coal powder suspended as dusts in a gas. The sheet metal may be cooled by air blast, liquid spray or fog. An electrically heated filament or injected hot powder particles may be used instead of the spark plug.

Filed: 1959-05-19
Abstract: 871,688. Aerials. ALFORD, A. May 19, 1959, No. 17041/59. Class 40(7) A directive aerial system comprises a transmission line, formed by a pair of parallel conductors and terminated in its characteristic impedance, across which are coupled a plurality of loop units spread along the line. In one embodiment, Figs. 1 and 2, the line consists of two parallel angle-section conductors 1 and 2 secured together at their ends by insulating spacer-bars 3. One end of the line is fed from a co-axial cable and the other end is terminated by a load 7 equivalent to the characteristic impedance of the line. Across the line are arranged as indicated a plurality of loop units each consisting of four links. The mid-points of the loops lie between the line conductors as shown more clearly in Fig. 2 and the loops, although they do not make contact with each other, overlap along the line. The complete length round each loop is made a half of the working wavelength (#) and the loop spacing along the line may be #/8. In a practical construction nine or more loops are provided and of the order of half the power fed to the line is taken out of it by the loops. In another embodiment (Fig. 3) the loops are shorter and each extends to one side only of the transmission line although, as may be seen, a loop such as formed by links 20, 21, is balanced by a corresponding loop (links 22, 23) extending on the opposite side of the line. This arrangement is stated to be useful where a shorter loop system is to be provided. The invention is not limited as to the shape of the loops and rectangular, double-rectangular (Figs. 5 and 6, not shown), or circular loops may be used. Maximum radiation is in the direction of the line and a typical radiation pattern (Fig. 7, not shown) is given.

Abstract: 1327332 Specula WELCH ALLYN INC 28 May 1971 [21 Dec 1970] 17991/71 Heading A5R A surgical speculum 10 comprises a pair of transparent blades 11, 13, the first blade 13 being pivotally mounted for movement towards and from the second blade 11, a depending post 15 extending laterally from the second blade, a longitudinally curved elongate light guide 17 of substantially uniform cross-section extending within the second blade from the junction of the post with the second blade to a position in which the guide lies substantially parallel with the longitudinal axis of the second blade, the curvature of -the guide being such that in operation light rays entering the guide at the junction thereafter only exceed the critical angle for total internal reflection at the distal-end surface of the guide. After insertion of the speculum into a body cavity, the physician moves the slide 12 along the post 15 by pushing against the finger-piece end 25' of the pawl 25 to separate the proximal ends of the blades. Catch 27 is engaged with one of the ratchet teeth 28 and the catch is held in position by the resiliency of the bridging portion 26, latching the slide in relation to the fixed blade 11. Lever 35 is depressed via fingerpiece 41 thereby rotating the movable blade 13 on its pivot pins 34 and hence changing the angular relationship of the blades 11, 13. The tongue 30 is biased by its resiliency against latch 40 so that the ratchet teeth 32 are successively engaged by the catch as the distal ends of the blades open. Pressure on the finger-piece 41 can be relaxed when sufficient distention is accomplished and the blades remain latched in their angular position. The light required for illumination of the body cavity upon observation is provided by a light carrier 45 which fits into a socket of the light-source handle 50. The light carrier includes a bundle of glass fibres (52), Figs 10, 11 (not shown) for transmitting light from the source at the end 46 to the end (53) adjacent to the face 18 of an optical surface of the light guide 17.
